BOTTLE CAP AND CAPPING PROCESS.

Application filed December '16, 1925, Serial No. 75,882, and in Germany February 18, 1925.

Our invention relates to capsules or seals for sealing the closed mouths of bottles, or similar containers, and has for its object to produce a novel capsule easily to be applied, and also consists in the method of applying such a capsule.

According to our invention the capsule or seal is made up of separate strips, preferably of a metal foil, such as tin foil, and these strips are placed crosswise over the mouth of the bottle, so that their free ends extend radially in various directions, whereupon the free ends are turned down and are pressed either singly or several together in succession against the neck of the bottle. The metal foils may be placed on a foundation of a thin coat of gelatine or other adhesive material.

The radially extending ends of the strips may be arranged in star-like form, and this may be done directly on the mouth of the bottle or in the special sealing device used, or at any other stage of the sealing operation.

In the accompanying drawing, in which we are showing our invention by Way of illustration, Fig. 1 shows a capsule composed of three strips of tin foil in crosswise arrangement, while Fig. 2 shows the same capsule when applied to the neck of a bottle, the body portion of which has been broken away.

According to the embodiment of our invention as shown in Fig. 1, the capsule, or seal, to be placed over the previously closed mouth of a bottle is made up of a plurality of strips in cross-wise arrangement so that the free ends of the strips extend radially in various directions, star-shape. In Fig. 1, three strips, a, b, 0 are shown arranged cross-ways, so that the middle portions of the strips form a thickened central part, into which may be impressed a symbol, or the like, as indicated at a in Fig. 1. iter these cross-wisely arranged strips have been placed on the mouth of the bottle, indicated at (Z in Fig. 2, with the thickened central layer directly on top, the radially extending portions of the strips are turned down and pressed against the sides of the bottle neck, so that they will smoothly lie against-the same as clearly shown in Fig. 2.

For making the strips adhere fast to the bottle neck, a thin coat of gelatine or another adhesive material may be provided on the strips or upon the bottle neck. Either the gelatine coat or the bottle neck may be moistened, before the ends of the strips are pressed against the neck so as to render the gelatine coat adhesive.

As compared with the known seals, the one according to this invention oiiers numerous advantages. The separate strips can be produced. very cheaply, easily and rapidly, without Waste. The strips can be applied to bottle necks of any diameter and they can be easily stacked and despatched. The strips may be dyed in difi'erent colors, so that in the finished seal the most Widely varied color schemes may be combined. Also, the strips may be variously shaped, for instance, the topmost strip may be made so as to correspond in the center exactly to the diameter of the mouth of the bottle.

We claim as our invention:

1. A. capsule for bottles and like containers, comprising a plurality of superposed strips arranged cross-wise so as to form a thickened central part, the free ends of said strips radially extending from said central part in various directions.

2. A capsule for bottles and like containers, comprising a plurality of superposed intersecting pliable strips forming a thickened central part, the free ends of the strips radially extending from said central part in various directions.

3. A capsule for sealing bottles and like containers, comprising a plurality of superposed intersecting strips of tin-foil forming a thickened central part, the free ends of the strips radially extending from said central part in various directions.

4. The method of sealing bottles and like containers, which consists in placing a plurality of strips one above the other in crosswise arrangement with their central portions over the mouth of the bottle, and pressing the radially extending free ends of the strips against the bottle neck.

5. The method of sealing bottles and like containers, which consists in placing a plurality of strips of suitable material one above the other in cross-wise arrangement with their central portions over the mouth of the bottle, applying to the neck of the bottle an adhesive substance, and then pressing the free radially extending ends of the strips against the bottle neck.

6. The method of sealing bottles and like containers, which consists in placing a plurality of strips of Variedly dyed metal foil in superposed cross-Wise arrangement over rangeinent over the mouth of the bottle with the mouth of the bottle With the central porthe central portions of said strips forming tions of said strips forming a thickened a thickened part covering the mouth, and part, and then pressing the free radially eX- pressing the free radially extending ends of I tending ends of the strips against the botsaid strips against the bottle neck. ll tle neck.
